The Webis Known-Item Question Corpus 2013 (Webis-KIQC-13) contains annotations for 2,755 questions posted on Yahoo! Answers. For each question, 2 annotators were asked to categorize the question as having a known-item information need or not, to identify a ClueWeb09 website representing the known item, and whether false memories are contained in the description of the need. The corpus represents the decisions of the annotators who had discussions for the few questions on which they did not agree initially.
